OI HICKORY, TENNESSEE, ASSIGNOBS, BY IESNE ASSIGNMENTS, TO DU PONT KAYON COMPANY, OF NEW YORK, N. Y, A CORPORATION 01' DELAWARE THREAD GUIDE Application filed Augult S0, 1988. Serial No. 302,968.

This invention relates to a thread guide and more particularly to a guide adapted to be used in a thread windin machine.

,Machines have been devised to wind thread on cones or other supports. These machines comprise a spindle on which a cone or other support receiving the thread is mounted, a thread guide mounted on a pivoted support and having one end resting on the cone or winding thereon, and means to reciprocate the guide across the cone so that a uniform winding is obtained. In the winding of the thread on the cone or other support, due to various reasons, such as the variation of the washboard and slippage occurring during and/or after knotting the ends of a broken thread of adjacent windings, numerous portions thereof, and especially during the initial stages of the winding operation, are loosely wound. The thread guide and the thread guide holder in traversing back and forth across the windings on the cone engage the loosely wound thread or loops thereof and cut or break it. In practice, the loops of the thread that are broken or out, since they are formed of previously wound thread, do not stop the operation of the winding machine. Thus, a cone of thread having broken threads is produced. A weaver, using such a cone of thread, when he comes to the broken thread must either stop the weaving machine and knot the ends of the broken threads, or, continue the operation of the machine producing a hole in the fabric. In the first instance, the stopping of the machine decreases production, while in thelatter instance, the fabric must either be cut, resulting in excessive waste, or classified as second grade or quality of material.

We haveofound that we can overcome the above-mentioned defects by providing a thread guide which, when it engages any loosely wound thread, will not break it but lay it down on the windings and permit thread to be wound thereover.

It is, therefore, an object of this invention to provide a guide adapted to be used in a thread winding machine of the usual type and having means whereby any loose threads engaged by said guide will be laid down on the windings and not broken.

Another object of this invention is to provide a guide adapted to be used in thread winding machines and comprising a notched button member adapted to guide the thread on to the cone and means adjacent said button member to lay down any loose threads elrligagiad by said guide withoutbreaking said t re Further objects will appear from the following description, appended claims and the accompanying drawings in which:

Figure 1 is a side elevation of a winding machine of the standard type and illustrating the manner in which the thread guide constituting this invention is mounted.

Figure 2 is a front elevation of the machine shown in Figure 1.

Figure 3 is a front elevation of the guide constituting this invention.

Figure 4 is a side elevation of the device illustrated in Figure 3.

Figure 5 is a top plan view of the device illustrated in Figure 3.

Figure 6 is a front elevation of a modification of a thread guide illustrated in Figure 3.

Figure 7 is a side elevation of a device illustrated in Figure 6.

Figure 8 is a top plan view of the device illustrated in Figure 6.

Referring to the drawings wherein like reference numerals designate like parts, and especially to Figures 3 to 5 inclusive, the reference numeral 1 designates a body member of the guide constituting this invention. The upper portion 2 of the body member 1 is disposed at an angle or offset to the middle portion 3 thereof and is provided with a recess 4, the edge of which is adapted to engage a groove 5 of a button 6. The button 6 is provided with a V-shaped notch 7 through which the thread passes on to the cone or other support and, since it is thicker than the body member 1, the front face of the button extends slightly beyond the front face of the upper portion 2 of the body member 1. Due to the inclination of the upper portion 2 of the body member, the button 6 always contacts when in position on the machine with the cone or the windings thereof and the body member is spaced therefrom.

Adjacent the upper extremity of the bod member 1 and formed integrally therewit (by stamping out of sheet metal) are two wire-like members 8 bent into the form illustrated in Figures 3 to 5 inclusive. These members 8 are curved rearwardly and, after extending a distance to the rear of the guide, are bent to form horizontal portions 9 and thence bent downwardly, as indicated by the reference numeral 10. The ends 11 of the downwardly bent portions 10 are securely fastened on to the rear of the body member 1 at any suitable point. If desired, the win portion may be made of wire and secure to the body member 1 by welding, soldering or the like instead of forming the entire device by stamping.

The lower portion 12 of the body member is also offset from the middle portion 3 and is provided with a foot or key portion 13 whereby the device may be mounted in a key-Way in the traverse bar of the winding machine. At some suitable point, the body member 1 has a struck-back portion 14 which is adapted to fit and slide on a member of the winding machine, whereby the guide is prevented from being dislocated during the operation of the machine. In the drawings, (see Figures 3 to 5) we have illustrated the ends 11 secured on the struck-back portion 14.

In order to more securely fasten the button 6 in the recess 4 and to remove any sharp edges or surfaces formed by the button 6, the recess 4, and the soldering of the wires 8 (if used) to the body member 1, various materials are applied between the recess 4 and the button 6 at the joints and surfaces adjacent thereto. We have found that adhesives which upon setting form smooth, hard surfaces produce satisfactory results. Among the adhesives that we have used and from which we have obtained satisfactory results are those formed from shellac, phenolic-condensation products, rubber and the like.

The button 6 is made of a material that is smooth, has a low co-efficient friction and will not damage the thread wound on the cone during its reciprocation thereover. It may be made from various materials and we have found that a guide made of glazed porcelain, hard rubber, phenolic-condensation products and the like produces satisfactory results.

The modification illustrated in Figures 6 to 8 inclusive is similar to the preferred form illustrated in Figures 3 to 5 inclusive. It differs therefrom, however, in that the curved or wing portions 8 formed integrally with the bgdy member 1 do not have the horizontal and downwardly bent portions of the wing members of the preferred form. In all other respects the guide member is similar to that illustrated in Figures 3 'to 5,

and further description thereof is deemed unnecessary.

As above set forth, the device is adapted to be used on a thread winding machine of the usual type which comprises a spindle l5, a'traverse bar 16 carried on a support 17, pivoted at 18 and carrying a weight at the lower end thereof (not shown). A reciprocatin g movement is imparted to the traverse bar 16 by means of a follower 19 keyed thereto and operating in a cam surface 20 of a continuous rotating roller 21. Since the specific details of the Winding mechanism do not form any part of this invention, further description thereof is deemed unnecessary.

The foot 13 of the body member is secured in a key-way 22 in the traverse bar 16 by means of a screw 23. The sprung-back portion 14 fits on and rides over a support 24,

whereby the button 6 is prevented from being dislocated from its normal position on the machine, namely, resting on the cone or windings thereof. Upon reciprocation of the traverse bar 16, the thread guide is reciprocated back and forth across the cone. The thread led through the various guides on the machine passes through the notch T of the button 6 on to the cone where it is uniformly wound. If, during the reciprocation of the thread guide across the cone, any loosely wound thread, such as a loop, is engaged thereby it will be engaged by the outwardly extending curved wing-like portions 8. Continued movement of the guide will cause the thread portion to slip along the wing-portions 8 whereby it will be laid down on the windings and covered and bound by subsequent windings. It is thus seen that the thread guide does not tear or break any loose threads engaged thereby, but lays them down and permits winding thereover.
